64-bit/66MHz Fibre Channel Host Adapter for Red Hat Linux Advanced Server 2.1

[张辉_1]

ProLiant Linux driver for 64-bit/66MHz Fibre Channel Host Adapter for Red Hat Linux Advanced Server 2.1


Installation




Login as the system administrator (root), download
the RPM to a directory on your hard drive and change to that directory.


To install the driver type:

# rpm -ivh cpq_cpqfc_RedHatAS21-.i386.rpm

NOTE: If the installation fails or if you see any warning or error messages, STOP, do NOT reboot the computer. The driver will not be operational and you must uninstall the driver by typing the following command:

# rpm -e cpq_cpqfc_RedHatAS21-

The removal of the RPM restores the original cpqfc.o module, builds a new initrd image with the previous (or no) module, and adds a new entry into /etc/lilo.conf or /boot/grub/menu.lst. You can then boot using the newest entry, or a prior known working entry.

The successful installation will replace the driver that shipped with Red Hat Linux Advanced Server 2.1 with the 2.1.2 version of the driver, create a new Initial RAM Disk Image (initrd) that contains the 2.1.2 version of the driver and modify /etc/lilo.conf to allow the Linux Loader (lilo) to boot the new ramdisk image. The installation of this RPM modifies the following files:

/etc/lilo.conf (or /boot/grub/menu.lst)
/etc/lilo.conf.bak-* (backup files)
/boot/grub/menu.lst.bak-* (backup files)
/boot/cpq-initrd-*.img-* (initrd images)
if you have multiple processors installed in your server expect:
/lib/modules/2.4.9-e.3smp/kernel/drivers/scsi/cpqfc.o
if you have a single processor server expect:
/lib/modules/2.4.9-e.3/kernel/drivers/scsi/cpqfc.o

Backups of your previous files will be kept in the /usr/src/COMPAQ/driver_backup directory.

The driver version can be verified by typing:
# grep version /proc/scsi/cpqfcTS/*
Expect output similar to:
Driver version = 2.1.2


The driver will be inserted in the Initial RAM Disk Image (initrd) and is automatically loaded every time the server boots.


To load the module use the insmod command, type:

# insmod cpqfc

Expect the following output if you have Symmetric Multi-Processing support enabled:
Using /lib/modules/2.4.9-e.3smp/kernel/drivers/scsi/cpqfc.o

Expect the following output if you have a single processor server:
Using /lib/modules/2.4.9-e.3/kernel/drivers/scsi/cpqfc.o

NOTE: You will experience error messages if the Compaq's 64-bit/66MHz Fibre Channel Host Adapter is not installed. Please ensure that the hardware is installed properly.

NOTE: If the hardware is properly installed and you observe error messages loading the modules, remove the entire RPM by typing:

# rpm -e cpq_cpqfc_RedHatAS21-

The removal of the RPM restores the original cpqfc.o module, builds a new initrd image with the previous (or no) module, and adds a new entry into /etc/lilo.conf or /boot/grub/menu.lst. You can then boot using the newest entry, or a prior known working entry.


To check whether the driver is loaded properly, type:

# lsmod

Expect to see the module name cpqfc displayed.


If you attempt to install the RPM on an unsupported system, you will get an error message. The driver will not be operational and must be uninstalled by typing the following command:

# rpm -e cpq_cpqfc_RedHatAS21-


Uninstalling the driver:

Uninstall using RPM by typing

# rpm -e cpq_cpqfc_RedHatAS21-

[Steven E. Protter]

If you are really in a jam:

rpm -e --nodeps cpq_cpqfc_RedHatAS21-

This will force the uninstall.

It may help,it may make things worse depending on dependencies.
